LINNAEUS E. BAKER, OF FORT WAYNE, INDIANA, ASSIGNOR T0 WAYNE TANK AND PUMP COMPANY, OF FORT WAYNE, INDIANA, A CORPORATION OF INDIANA.

STABILIZER non DRAIN PIPES.

Application filed January 3, 1920.

To all whom it may concern:

Be it known that I, LINNAEUS E. BAKER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented new and useful Improvements in Stabilizers for Drain Pipes, of which the following is a specification.

My invention relates to pipes adapted to drain liquids from vessels, and particularly to means for securing a quiet and even flow from the vessel into the pipe.

It is well known that with an open ended drain pipe, the draining liquid forms a vortex thru which air enters the pipe along with the liquid. This my improvement prevents.

The particular embodiment of my invention selected for illustration, is the upper end of an upright drain pipe adapted to extend into a vessel for liquid.

Figure 1, is a vertical axial section of the upper end of such a pipe with the stabilizer in position for use, and

Fig. 2, is a top plan view of the stabilizer, with the spider shown in dotted lines.

In the drawings, A, is a drain pipe, with its upper end a, of greater internal diameter forming a shoulder a A stabilizer B, is formed of a shield portion 6, preferably of the same shape and size as the outside'of the pipe A, and a spider 6 preferably integral with the shield on the under side thereof. The webs of the spider are so formed as to fit tightly against the sides of the portion a, of the pipe and seat upon the shoulder a when the stabilizer is pressed into position for use, in the pipe. The webs are preferably cut away at the top to below the level of the top of the pipe to prevent capillary attraction causing the liquid in the vessel (notshown) in which the drain pipe is to be used, from flowing out to below the level of the upper end of the pipe; and such notched-in portion Serial No. 349,329.

of the webs are designated as 6 Where exact draining is not important no notches 6 need be made.

The liquid will flow into the top of the pipe under the shield b, from all sides and pass downwardly as indicated by the arrows (Fig. 1) with a quiet even flow.

I claim as my invention and desire to secure by Letters Patent of the United States:

1. In combination with a drain pipe a shield rigidly secured to and spaced from the opening in said drain pipe by means of a spider secured to the under side of said shield, said spider adapted to contact with the inner surface of said pipe, to hold said shield rigidly in position.

2. In combination with an imperforate drain pipe a shield rigidly secured to and spaced from the opening in said drain pipe by means of a spider secured to the under side of said shield, said spider adapted to contact with the inner surface of said pipe,

to hold said shield rigidly in position.

8. In combination with an upright drain pipe, a shield for the top end of the pipe, a spider integral with and, on the under side of the shield, the spider adapted to fit securely against the inside walls of the pipe and maintain the shield in spaced relation to the end of the pipe, and notches in the webs of the spider next the shield to a point below the top of the pipe.

4. In combination with an upright drain pipe having its upper end of greater internal diameter than the main portion, a shield for the top end of the pipe, a spider integral with and on the under side of the shield, the spider adapted to fit securely against the inside walls of that portion of the pipe having the greater diameter and to seat upon the shoulder at the bottom of said enlarged portion in such a manner as to maintain the shield in spaced relation to the end of the pipe.

pipe, and notches in the Webs of the spider next the shield to a point below the top of the pipe. I

In testimony whereof I have hereunto set 15 my hand in presence of two subscribing Wit- IIGSSGS.
